Application filed April 4, 1918. Serial No. 226,764.

' raw materials are melted down and the mol ten glass is kept at therequired high temperature by a stream of hot gases circulatin over thebatch.

he accompanying drawing illustrates somewhat diagrammatically in ahorizontal sectional view a furnace embodying the present invention.

In this furnace, the hot gases are intro duced through an openin A(called burner) in the rear wall 0 the furnace; the raw materials arefed through the openings B, B. The space R, located at the side of theflue S, is the melting-space, wherein the raw materials are convertedfrom the solid condition into the liquid form. The walls of the spaceinto which opens the burner, where the glass is in the molten condition,have a numberof so-called workingopenings C, through which the moltenglass is taken up by the workmen. 'In front of each workin -opening is aso-called floater D or like (ivice having for its object to withhold theslag and other impurities in a manner well-known in the art. The hotgases, after flowin through the furnace, are discharged througfii theflue S, which is in communication with the furnace by an opening inthefront wall, 2'. e. in the wall opposite the burner A. The flame fromthe burner is fed by liquid fuel introduced into the furnace undersuitable pressure.

Now, the present invention is characterized in that the working-space isat the side of the burner andthe melting-space at the side of the flue,in which feature it is clearly distinguished from the known furnaces, inwhich the melting space is at the side of the burner and the workingspace at the side of the flue.

The new arrangement has some very important advantages over the old one.

In the first place the solid raw materials or batch are fed into thefurnace at a point where the temperature of the flame is highest, andthe molten lass from the melting space, according to t e removal of thecontents of the working space by means of the pipes or tubes usuallyemployed, gradually flows to the zone where the temperature is lowest.It should be understood that a flame fed by liquid fuel under pressureis hottest at a point-at a considerable distance from the burner, 'sothat by suitably regulating this pressure, it is always possible to havethe zone of the highest temperature coincide with the melting space.With this arrangement the batch is melted down in an efiicient manner,whereas no unnecessarily high temperatures occur in the working-outcompartment.

A furtheradvantageous feature of the new furnace is the fact that thecombustible (such as for instance tar) from the burner enters a spacewhere the glass hasa very high temperature, so that no condensation ordeposition of carbon can takeplace, as is the case in the known furnaceswherein the combustimass is to be feared. Finally, the usual furnaceshave the ob 1ectionable feature that the finely reduced parts of the rawmaterials may be blown away by the high speed stream of hot gases tionandin what manner the same is to be performed, I declare that .what Iclaim is:

A glass furnace having a melting compartment and a working-outcompartment in communication therewith and located sub- PatentedFeb.4l,f91l9.
